From the viewpoint of Perl 5, it's a feature, but from the viewpoint of Perl 6, it's a bug. Perl 6 will distinguish AUTOMETH from AUTOSUB. (Those are the declarative forms, which return references. Perl 6 will distinguish those from the defining forms, which are spelled AUTOMETHDEF and AUTOSUBDEF, and which may only be called on predeclared (or autodeclared) names to supply a missing definition.)

Yes, once you've taken a reference to a method, it's essentially a sub ref at that point, so the Perl 6 equivalent of your code works as you'd expect. In fact, the standard dispatchers are defined in those terms. But the standard dispatchers will be able to keep subs and methods straight to the extent that you wish them to (which, by default, is up to the point that a method turns out to be completely missing, and you wish it to "failover" to looking for a multi-sub instead).

Went to join the gridlock to see it
Held an eclipse party
Watched a live feed
I cn"t see tge kwubosd to amswr thus
I tried to see it, but 8000 miles of rock got in the way
What eclipse?
Wanted to see it, but they wouldn't reschedule it
Read the book instead
